Hi Charl.  my solar knowledge is not too hot  (!).......

but is the  cloudy veil like structure in your first picture  an actual 'former' prominence  but seen from straight-on as opposed to 'edge-on' when on the limb ?

I have often wondered.  Cheers,  and nice pictures.

That's right, it is basically a prominence seen against the brighter sun so it appears darker and is called a filament.

Thanks Stu,    so....... that means they must dance around on the surface as they do on the limb....   I can feel a potential animation coming on.....

Roll on the endless azure skies ..........
